Abstract
An Orthogonal Frequency Division Multiplexer (OFDM) transmitter and receiver apparatus consistent with certain embodiments of the present invention receives data to be transmitted and maps () a first portion of the data to a first polarization state and a second portion of the data to a second polarization state. A first transmitter () transmits the first portion of the data as a set of first OFDM subcarriers using an antenna () exhibiting a first polarization. A second transmitter () transmits the second portion of the data as a set of second OFDM subcarriers using an antenna () exhibiting a second polarization, wherein the first polarization is orthogonal to the second polarization. A receiver apparatus uses a first antenna () exhibiting the first polarization and a second antenna () exhibiting the second polarization. A first OFDM receiver () receives a first set of polarized OFDM subcarriers from the first antenna () while a second OFDM receiver () receives a second set of polarized OFDM subcarriers from the second antenna (). A decoder () decodes the first and second sets of OFDM subcarriers and combines them into a stream of data.
